摘要
Background: Biotransformed bufadienolides are new kind of cytotoxic products with novel structures. @@@ Method: Herein, 3D-QSAR analyses were performed on bufadienolides using CoMFA and CoMSIA to learn the structure-activity relationship and the mechanism of action of these compounds. The cross-validated q(2)value of CoMFA is 0.648 and q(2) value of CoMSIA is 0.635. The non-crossvalidated r(2) value of CoMFA is 0.963 and r(2) values of CoMSIA is 0.961. The 3D-QSAR models we obtained were illustrated through CoMFA and CoMSIA contour plots. @@@ Results: That will be valuable in predicting cytotoxic activities against cancer cells, and could be used to design potent anticancer drugs.
